for RS232 or USB and CNI for Ethernet TCP/IP), you can interact with other home automation systems, or with applications on devices like Android, iPad or iPhone. The C-Bus protocol was developed using the OSI 7 layer reference model. C-Bus supports a number of interfaces such as RS232 and TCP/IP and makes these protocols available to third-party companies. C-Bus interface specifications are available through the C-Bus Enabled Program, however it is necessary to agree to a license agreement. Geographic use of C-Bus and Compatibility C-Bus as a home automation and commercial building lighting control system is used primarily in Australia, China and New Zealand. C-Bus is currently available in Asia, the United Kingdom (installed in Number 10 Downing Street, Wembley Stadium and Manchester City Football Club), Russia and a number of other countries are now using this system. The C-Bus wireless (RF) system and wired C-Bus Occupancy Controllers can be retrofitted using the existing mains wiring. C-Bus is compatible with Translink C-Bus Gateway, OPC, DALI, DSI, BACnet, TCP/IP, Control4, Crestron, AMX, RTI, LonWorks, ModBus, Charmed Quark Controller, the Comfort Intelligent Home System and some other protocols through interfaces.
